Abstract

A method for hot hydrostatic pressing by means of working liquid which tends to become unstable within a transition time when in contact with a blank heated to a high working temperature and at a pressure lower than the liquid's stabilization pressure. The pressing of the blank heated to the high working temperature is carried out by raising the pressure of the working fluid to said stabilization pressure for a time shorter than the transition time. This is achieved by surrounding the heated blank by a cover adapted to delay the contact between the heated blank and the working liquid until the pressure in the working chamber is raised.
